Frequently asked questions
+Can I merge PDFs for free?
Yes — drop multiple PDFs in and download a single merged file. No page limits and no watermark.
+Can I split a PDF into single pages?
Yes — extract every page as its own PDF, or select a page range to export.
+Is my PDF uploaded anywhere?
No. Every operation (merge, split, convert) runs inside your browser using pdf-lib. Your documents never touch our servers.
+Will the merged PDF lose quality?
No re-rendering happens during merge — pages are copied byte-for-byte, so quality is identical to the source.
+What's the largest PDF I can work with?
Free supports up to 100 MB per file. Pro lifts this to 500 MB for thesis-sized PDFs.
+Is it safe for university dissertations?
Yes — because everything is local, sensitive academic work stays on your device. Ideal for student dissertations and group projects.
